To be very brief, Karl Friston’s “free energy principle” says that the brain is an “inference machine” or “prediction machine” that uses Bayesian probability reasoning and is motivated to act by an inference seeming not true or “surprising” to it.
The free energy principle is a straightforward way to explain what FIML practice does, how it does it, and why it works differently than any other form of psychotherapy and in many significant ways why it works better.
A psychological “complex,” “neurosis,” “personality disorder,” or “persistent thought,” call it what you will, affects human behavior by being or having become a nexus of thoughts, ideas, perceptions, feelings, interconnected neurons and chemistry.
The same is true for any personality trait or skill, including very positive ones.
In Friston’s free energy terms, the psychological elements described above are surrounded by Markov blankets.
That means they are isolated or protected systems with their own variables. These protected systems (protected by Markov blankets) are hard to change because they have their own sets of rules and habitual inputs and outputs.
And that makes them stubborn candidates for most forms of psychotherapy, especially psychotherapy that requires a therapist. One reason for this is time & expense. A second reason is it is difficult for the patient to change without therapeutically experiencing for themself the complex or trait in real-world situations.
The key here is therapeutic experience in the real-world of the unwanted trait or complex that requires change.
The third reason most psychotherapies are ineffective is it take time to penetrate their Markov blankets.
What FIML does is penetrate the Markov blanket enshrouding a complex with a series of small pricks. Each prick in the blanket is small, but each prick also allows some of the valence (gas) inside the blanket to escape.
FIML slowly punctures the Markov blanket with many small pricks, eventually causing it to collapse.
Once it has collapsed, the energies that were trapped inside it can be used for other things. In this way FIML optimizes even non-neurotic psychology by removing pockets of inefficiency held within psychological Markov blankets.
By using only small pricks to penetrate Markov blankets, FIML allows people to gradually and painlessly see what needs to be changed, why, and how to do it. Since FIML works in real-time real-world situations, even very small insights can bring about large changes.
